Today, we will explore the male and female reproductive systems. Can anyone tell me what primary structures are present in the male reproductive system?

Exactly! The testes produce sperm and hormones. What about the female reproductive system?

Right again! Understanding these structures is crucial because they play different roles in reproduction. Can anyone summarize a function of the ovaries?

Good! Remember, the terms 'ova' and 'ovum' refer to eggs. Let’s use the acronym 'REPO' for reproductive organs to help us remember!

To recap, we covered the key components of the reproductive systems: testes for males produce sperm, and ovaries for females produce eggs. Any questions before we move on?

Let's discuss how gametes are formed. Who can explain what spermatogenesis is?

Correct! And how does it differ from oogenesis?

Exactly! Remember, during spermatogenesis, several sperm are produced from one stem cell, while oogenesis produces one ovum and polar bodies. How can we memorize this?

Great tips! In summary, spermatogenesis leads to multiple sperm, while oogenesis yields one ovum. Let's continue with some exercises to reinforce this.

Now, who can outline the phases of the menstrual cycle?

Excellent! What role do hormones play in this cycle?

Absolutely! To remember the phases and their functions, we can use the mnemonic 'My First Ovarian Lick'—Menstrual, Follicular, Ovulatory, Luteal! Can someone summarize why understanding this cycle is important?

Exactly right! A strong grasp of these concepts will serve us well.

Let's discuss fertilization. What happens during this process?

Correct! This forms a zygote, which eventually develops into an embryo. What’s the next step after fertilization?

Exactly! We can remember this by thinking 'Fertilize First, Embed Next.' Any thoughts on what happens once it's embedded?

Wonderful! The placenta is crucial for nutrient transport. To sum up, we've discussed the definitions of fertilization, implantation, and the role of the placenta.
